Naturlatex is made with independent springs, each contained in a bag of hypoallergenic material, allowing for differentiated compression according to the weight and protuberances of the body. The padding consists of latex on both sides. The “box” system stiffens the mattress at the sides, for greater comfort when sitting on the edge or when getting out of bed. The fabric is in a cotton and linen blend and is quilted with a wool blend for the winter side and a cotton blend for the summer side.
